Description

[Detailed Description of the Invention] [Industrial field of application] The present invention selects fine grains having a small grain thickness (immature grains, dead rice, etc., also referred to as waste rice) from grains and The present invention relates to a vertical grain sorting and weighing machine for weighing the removed grain (sized grain), and particularly to a fine grain extracting device in the vertical grain sorting and weighing machine for taking fine grains out of the machine.

[Prior Art] A spiral is concentrically provided in a sorting cylinder erected in a machine frame, and a large number of long holes (slits) are provided in the peripheral surface of the sorting cylinder while the grains are being conveyed by the spiral. For a vertical type particle sorting machine for selectively removing fine particles, for example, Japanese Patent Publication No. 59-1426.
It is proposed in No. 9 bulletin.

[Problems to be Solved by the Invention]

In such a sorter, fine particles leaked from the long holes of the sorting cylinder are dropped into a fine grain trough provided around the lower part of the sorting cylinder, and by fine grain scraping blades rotating with the sorting cylinder. It is scraped out from the fine grain discharge port, but the fine grain discharge port is
Due to the structure, it is installed at a lower position by tilting further from the vicinity of the lower end of the sorting cylinder, so it cannot be put directly into a paper bag (30 kg capacity), etc., and it is discharged with a basket (rather) laid. It took a lot of work because it required the work of receiving it in the receiving box and replacing it with a paper bag many times in a short time.

The present invention is a fine particle extracting device of a vertical sorting and weighing device that can directly insert fine particles that have been selected and removed into a paper bag or the like, further, depending on the installation position of the machine in the preceding process,
Provided is a fine grain extracting device in a vertical grain type sorting and weighing machine capable of changing the fine grain extracting position.

[Action]

Grains thrown in from the top of the spiral tube gradually flow down while coming into contact with the inner peripheral surface of the perforated wall selection tube under the centrifugal force of the spiral tube, while a large number of grains are provided around the perforated wall selection tube. Fine grains having a grain thickness smaller than the width of the long holes leak from the holes, reach the fine grain discharge port, and are conveyed upward through the supply port of the fine grain feeder. When the low-order outlet provided at the top of the fine grain feeder is open, all the fine particles fed above are discharged from the low-order outlet to the outside of the machine barrel, and stored in a paper bag prepared in advance. Be packed. In addition, when the lower-side outlet is closed, fine particles are further sent up, flow down the downflow gutter from the higher-side outlet, and are discharged to the outside of the machine barrel from another corner inside the machine casing, such as a paper bag. Be packed in. On the other hand, the grains that have not been selectively removed (grain size) are sent to a weighing tank from a grain size discharge port provided at the bottom of the perforated wall sorting cylinder via a grain lifting machine. Then, the grain is started to be supplied from the weighing tank to the bag body by the operation of the discharging device, and the discharging device is closed by the desired weight detection signal from the weighing machine to complete the weighing.
